All-perovskite tandem solar cells have shown great promise in breaking the Shockley–Queisser limit of single-junction cells. However, efficiency improvement all-perovskite is largely hindered by surface defects induced non-radiative recombination loss Sn–Pb mixed narrow bandgap perovskite films. Here, we report a reconstruction strategy utilizing polishing agent, 1,4-butanediamine, together with passivator, ethylenediammonium diiodide, to eliminate Sn-related and passivate organic cation...
Four of nine tetraalkylammonium-based amino-acid ionic liquids prepared in this work show lower viscosities than all amino acid-based found the literature and their reversible CO2 absorption approaches 0.5 mol per liquid.
Abstract The elimination of methylammonium (MA) cation from mixed tin–lead (Sn–Pb) narrow‐bandgap (NBG) perovskites is an effective approach to enhance the operational stability all‐perovskite tandem solar cells (TSCs). Unfortunately, uncontrolled nucleation and crystallization processes MA‐free Sn–Pb usually lead inferior film quality device performance. Herein, a bimolecular modulation strategy reported by using guanidine thiocyanate (GuaSCN) aminoacetamide hydrochloride (AHC) together as...
Fifteen novel amino acid ionic liquids (AAILs) were prepared by the combination of several tetraalkylammonium cations with four anions ([Gly], [L-Ala], [β-Ala] and [Val]).The asymmetry is shown to have a significant influence on viscosity composed anions, especially for triethylbutylammonium ([N2224])-based that viscosities lower than 60 mPa s, lowest being only 29 s. The low tetraalkylammonium-based AAILs are further demonstrated improve apparently reaction mass transfer rates CO2 in liquids.
By grafting butyl or ethyl onto tetramethylethylenediamine, quaternary ammonium salts with two positive charge centers were formed at the first step. Metathesis Ag(2)O followed. Through neutralization glycine, l-alanine, valine, a series of new ditetraalkylammonium amino acid ionic liquids (DILs) for CO(2) capture generated. The structures DILs, as shown in Figure 1, verified by using (1)H NMR and EA. These DILs found to be quite high viscosity which militated against their industrial...
It is very attractive that noncorrosive Brønsted acidic ionic liquids (BAILs) are used as catalysts in liquid catalyst-based reactive distillation columns, which avoids the technical difficulties raised from solid or corrosive mineral acids. The kinetics for esterification of n-butanol with acetic acid using BAILs was therefore studied systemically, to explore possibility BAIL-based catalytic processes. effects various parameters such temperature, catalyst loading, and molar ratio reactants...
Abstract Defective perovskite surfaces severely limit the development of inverted solar cells (PSCs). Here, impacts surface treatment are systematically investigated with organic ammonium salts, namely piperidinium iodide (PpI) and piperazinedihydroiodide (PDI), on performance formamidinium‐cesium (FACs)‐based PSCs. These results indicate that PpI, its high dipole moment, tends to form 1D structures surface, which hinders electron transport. By contrast, PDI post‐treatment does not lead...
Two-phase reactions involving microdroplets have gained significant attention in recent years due to their unique ability catalyze and accelerate that typically do not occur under standard conditions by leveraging chemical physical effects at the micrometer-scale interface. In this work we innovatively developed a scaled-up microdroplet reactor for efficient resource utilization of CO2. The reaction liquid is sprayed form mist (d32 < 20 μm), facilitating complete contact with gaseous We...

Abstract Achieving high efficiency over large areas remains a significant bottleneck in commercializing perovskite solar cells (PSCs). Recent advancements passivation technology, especially using self‐assembled monolayers (SAMs) to address buried interface defects, have been instrumental boosting the of PSCs. However, SAMs' compactness, uniformity, and wettability are crucial factors influencing quality films. This study presents layer based on NiO x /mesoporous Al 2 O 3 sponge as carrier...
